Section 2 — Control Panel Descriptions
External Interface Subpanel
The External Interface subpanel (Figure 2-18), located at the left
end of the upper control panel, provides selection of the type of
interface to be used to communicate with external devices.
The buttons on the subpanel perform the following functions:
The EDIT button enables or disables editor access to the switcher.
Initially pressing the button illuminates it and allows external
control of the switcher through the Editor port. Pressing the
button a second time turns off the button lamp and disables editor
control of the switcher. With
EDIT off, editor protocol messages
that affect the switcher are still acknowledged by the switcher,
although it does not act under Editor control. For example, the
switcher will still send status information to the editor.
NOTE:
An editor cannot control the
EDIT
button via software protocol.
In addition, the
EDIT
button does not affect communication through the
other serial ports.
